Quick Answer
A deductible is what you pay before your plan starts paying. A copay is a fixed amount for a covered service. Coinsurance is a percentage of the cost you pay, usually after your deductible is met. All three are forms of cost sharing, and they can apply together on the same bill depending on your plan and the service.
Review Bill Details
Compare your bill and EOB against your deductible, copay, and coinsurance before you call.
What is cost sharing?
HealthCare.gov describes cost sharing as the share of costs for covered services that you pay out of your own pocket. Deductibles, copays, and coinsurance are all forms of cost sharing.
A helpful way to picture it: your premium is what you pay to have the plan at all, like a subscription fee, while cost sharing is what you pay each time you actually use care.
What do deductible, copay, and coinsurance mean?
TermWhat it usually meansWhat to check
Deductible
The amount you pay for covered services before your plan starts to pay.
Check your plan documents or member portal for your specific deductible amount.
Copay
A fixed dollar amount you pay for a covered service, usually after your deductible is met.
Confirm the copay amount for that specific type of visit, since it can vary by service.
Coinsurance
A percentage of the cost of a covered service you pay, usually after your deductible is met.
Compare the percentage shown on your EOB with your plan documents.
Out-of-pocket maximum
The most you have to pay for covered services in a plan year. After you reach it, your plan pays 100% of covered services.
Check how much you have already paid toward this limit this year.
Premium
The amount you or your employer pays for your health plan, usually monthly, regardless of whether you use care.
This is separate from your deductible, copay, or coinsurance.

A worked example
- 1Your plan has a $2,000 deductible and 20% coinsurance after the deductible.
- 2You have a procedure with a $5,000 allowed amount, and you haven't paid anything toward your deductible yet this year.
- 3You pay the first $2,000 yourself, which satisfies your deductible.
- 4Of the remaining $3,000, your coinsurance is 20%, so you pay $600 and your plan pays $2,400.
- 5Your total for this claim is $2,600 ($2,000 deductible plus $600 coinsurance), unless a copay applied instead of coinsurance for part of the visit.
What this means for you
This is one illustrative example, not a prediction of what you will owe. Your own deductible, coinsurance percentage, copay amounts, and allowed amount will be different. Compare your own EOB and bill using the same steps.
How do these amounts work together?
Whether a copay, coinsurance, or both apply to a specific visit depends on your plan and the type of service. Some plans charge a copay for an office visit regardless of the deductible, while other services go entirely toward the deductible and then to coinsurance.
Once your total cost sharing for the year reaches your plan's out-of-pocket maximum, HealthCare.gov says your plan pays 100% of the costs of covered benefits for the rest of the plan year. Your premium does not count toward this limit.
Where do I find my actual numbers?
Your specific deductible, copay, coinsurance, and out-of-pocket maximum are listed on:
- Your plan's Summary of Benefits and Coverage.
- Your insurer's member portal or mobile app.
- Your Explanation of Benefits for a specific claim.
- Your insurance ID card, for some copay amounts.
What questions should I ask?
- What is my current deductible, and how much have I already paid toward it this year?
- Is this specific service subject to a copay, coinsurance, or both?
- What is my out-of-pocket maximum, and how much have I already paid toward it?
- Was the allowed amount used to calculate my share, or the billed amount?
- Can you send this in writing so I can compare it with my bill?
What mistakes should I avoid?
Watch out for these common mistakes
- Assuming a copay and coinsurance are the same thing
- Paying a bill without checking whether the deductible was already met this year
- Not asking whether a service is subject to cost sharing at all
- Confusing the billed amount with the amount cost sharing is based on
- Not tracking progress toward the out-of-pocket maximum
- Assuming the premium counts toward the deductible or out-of-pocket maximum
When should I use PapaShield tools?
Use tools when:
- You want help comparing your bill against your deductible and coinsurance.
- You need questions to ask the billing office or insurer.
- Your bill and EOB show different cost-sharing amounts.
- You want to organize documents before disputing a charge.
Frequently asked questions
What is the difference between a copay and coinsurance?
A copay is a fixed dollar amount for a covered service. Coinsurance is a percentage of the cost of a covered service. A plan may use one, the other, or both depending on the type of service.
Do I pay the deductible before or after a copay?
It depends on your plan. Some services require a copay regardless of whether the deductible is met, while others apply toward the deductible first. Check your plan documents or ask your insurer how a specific service is handled.
What happens after I reach my out-of-pocket maximum?
HealthCare.gov says that once you reach your out-of-pocket maximum, your plan pays 100% of the costs of covered benefits for the rest of the plan year.
Does my premium count toward my deductible?
No. A premium is what you pay to have the plan, usually monthly, regardless of whether you use care. It is separate from your deductible, copay, coinsurance, and out-of-pocket maximum.
Does seeing an out-of-network provider change these amounts?
Usually yes, and often significantly. Out-of-network care commonly comes with a higher deductible, higher coinsurance, or no coverage at all, depending on your plan. Check your plan documents or ask your insurer before an out-of-network visit if possible.
What is the difference between a family deductible and an individual deductible?
An individual deductible applies to one person's costs. A family deductible is a combined amount that can be met by one family member's costs or a combination of several. Many family plans have both, so check how your specific plan structures it.
Can PapaShield tell me my exact deductible or coinsurance amount?
No. PapaShield does not have access to your plan details. Your insurer, plan documents, or member portal are the source for your specific numbers.
